Ancillary studies that complement the objectives of TrialNet studies are strongly encouraged. Researchers can submit proposals for access to archived samples, subjects seen at a single center (for access to subjects seen at multiple centers, see Living Biobank above), or subject data. Learn More >

Data Sets

The National Institute of Diabetes and Digestive Disease (NIDDK) Central Data Repository (CDR) is a web-enabled resource available to researchers and the general public. The CDR warehouses clinical data and study documentation from NIDDK funded research, including such landmark studies as the Diabetes Prevention Trial Type 1 (DPT-1, the forerunner of TrialNet), The Diabetes Control and Complications Trial (DCCT, 1983-93) and the Epidemiology of Diabetes Interventions and Complications (EDIC, 1994-present) follow-up study which has been ongoing for more than 20 years. The CDR also houses data from over 7 million biospecimens representing 2 million subjects.
